Biology · Secondary 4 · Medium · Factors affecting transpiration

- Decreases, because water potential gradient between leaf and air is smaller
- Decreases, because stomata close in moving air
- Increases, because water potential gradient between leaf and air is steeper
- Remains the same, because humidity and wind have opposite effects
